I'd like to setup an internal closed network (no internet access) from a storage devices loaded with ebooks for multiple people using multiple types of devices. I'd like to be able to share those epubs with all these devices (more than 6) is this possible using Adobe Digital Editions?

Does this type of network/sharing violate DRM?

What would be the best way to load ebooks onto this network if it's possible at all?

This pass-hash system is a new option beyond the “identity based” system that was already supported with the use of an Adobe ID account to authorize a limited number of devices. This pass-hash system embeds an encrypted (or “hashed”) version of a user name and/or password into the ebook file. Any user who receives a copy of the file and knows the username and password associated with the item can read the eBook. Adobe calls this a form of “Social DRM” because the eBook and password info can be shared with others and is not limited to a specific number of authorized devices. (Note that the release of this system does not imply a change to the concurrent device limit used in the more popular identity based DRM option.)
